gas bike

I just bought new clutch pads. and they keep on slipping. I keep having to tighten the clutch and I even had to go so far that I had to stick a solid peice of metal in between the metal pin that pushes in the clutch.. I used break cleaner to clean up the area before i installed the pads. but its...

when i get into higher speeds on my 80cc beach cruiser, I hear a fast knocking sound and would like to know if I should be worried about that? or what is causing it?
